Chances are you’re one of the millions of people who have fallen victim to the addictiveness and utter ridiculousness of Dubsmash. And if you’re not, you probably will be by the end of this page.

The app — which lets you lip-sync to songs, movie quotes, and more — has been consistently entertaining us since it launched last November. But what we really love is watching celebs try their hands (or mouths, in this case) at nailing the perfect dub.

We’ve rounded up 13 of the best celeb Dubsmash clips and ranked them by hilarity. Check it out:

The supermodel and her baseball stud BF tackled the classic “Step Brothers” quote where Will Ferrell can’t understand if his interviewer’s name is Pam or Pan. Kate and Justin’s delivery is spot-on but lacks some spunk. More pizzazz, plz!

Noticing a tag-team trend? That’s because partnering up on Dubsmash is always a hit, like when Khloe and Kylie reenacted this hilarious Vine. We especially love the way Kylie gives some major ‘tude. They love each other, ok bitch?

Lena makes a strong case for why she should appear on “Lip Sync Battle” with this pitch-perfect rendition of Alanis Morisette’s vengeful “You Oughta Know.” And we love how Jack — shirtless and creepin’ behind her — chimes in for just a moment.

Upon first viewing, we thought Josh missed the point of the app by forgetting to mouth the words. But then he threw us for a loop with his unique take on Mel Gibson’s “Braveheart” battle cry: “They may take our lives, but they’ll never take...OUR FREEDOM!” Bonus points for originality.

How do we love this? Let us count the ways. There’s the flawless sunglasses, the way Rih Rih glances over her shades and stares down the camera as she imitates Seth Rogen in “Pineapple Express,” and the even more perfect way her friend chimes in at the end.

The “Pretty Little Liars” star is a Dubsmash pro — look no further than this seriously LOL-worthy reenactment of a famous Vine. The way she throws her head back at the perfect moment and her delivery of the line “deez nuts” deserve an Oscar.

Try not to watch this more than once, we dare you. Earning the number one spot is Fifth Harmony’s Camila, whose impression of Donkey from “Shrek” is *everything.* The way she sassily flips her hair, stares you down, and spits the word “waffles” is truly captivating stuff. Please make more of these, Camila!
